I am really glad with how this project turned out. At first I was pretty overwhelmed by the code and equations. However, after I watched Dan Shiffman’s video “Coding Challenge #55: Mathematical Rose Patterns” I had a much better understanding of the assignment. I decided that my two aspects of variability would be the amount of stems in the flower, and the rotation. I started out using vertex, but decided to change it to point since it had a much smoother look. I also wanted to make it so that it could rotate as much as possible, and have a massive amount of stems. I opted out of using color because I thought that it gave the image a more simplistic look.
